The gravity station data total 9416 records. This data base was received in March
1997. Principal gravity parameters include Free-air Anomalies which have been adjusted
to the International Gravity Standardization Net 1971 (IGSN 71). The gravity anomaly
computation uses the Geodetic Reference System 1967 (GRS67) theoretical gravity formula.
The data are randomly distributed within the area approx. bounded by 61 to 66 degrees
latitude and 144 to 159 degrees longitude in the interior of Alaska, In addition,
the data has been gridded and maps have been recently published through the USGS,
Map GP-1016.
